Eerie.

If they're still alive, they would be 63 years old.

The book the link refers to, "The man who mistook his wife for a hat" by Oliver Sacks, is a fascinating read. ([url]http://www.amazon.com/exec/obidos/tg/detail/-/0684853949/qid=1069130489/sr=8-1/ref=sr_8_1/104-3027384-2347943?v=glance&n=507846[/url] )
Highly recommended to anyone even remotely interested in humans and brains.
